The coldest schedule this winter

The coldest winter in 2023-2024 is March 9, 2024, and June 9, 2024-June 7, 2024.

Everyone said that "March 1949 was walking on the ice", indicating that March 1999 to April 1999 was the coldest period in winter, with ice and snow everywhere and rivers frozen. This period of time is from the end of November to the middle of December in the lunar calendar, corresponding to the slight cold and severe cold in the 24 solar terms.

Calculation method

The correct algorithm of "counting nine" begins from winter to the first nonunion day in the future. Therefore, the specific date of "September" every year is not fixed, depending on the first nonyl day after the winter solstice.

Another view is that the number nine is counted from the date of winter solstice, and the specific time of nine is fixed every year from the date of winter solstice, and each nine is fixed on the ninth day, 18 and the 27th day after winter. The algorithm of "counting nine" from winter to the sun is not very accurate.

The original algorithm of "Counting Nine" is to count from winter to the first nonunion day in the future (referring to the days prefixed with "nonunion" in the ancient "law of observing cadres and supporting the day"). As the saying goes, "Summer solstice is three years old, and winter solstice is nine." Because of this trouble, it was later counted from the winter of solstice.
